Non-institutional stock holders

I am curious who are the non-institutions (and non-funds) holding stocks. For example, I find it hard to believe that 38% of INTC is owned by individual investors (62% is held by funds):http://finance.yahoo.com/q/mh?s=intc&ql=1

I guess I asked the question for a couple reasons. First, I thought no one buys stocks directly anymore since it's easier to diversify thru ETFs and mutual funds. But it looks like one third (or so) of many largecap shares held by individual investors. For Walmart, it's more than two thirds:http://finance.yahoo.com/q/mh?s=wmt&ql=1
(only 31% is held by funds).
Still it's surprising that for example, almost half of BAC shares are held by individuals:http://finance.yahoo.com/q/mh?s=bac&ql=1
(or maybe it's the government holding those shares

My second question is: what does it say about a stock that a large/small % of shares are held by individual investors? I imagine most people want to own high quality dividend stocks. But then plenty of people seems to be sticking with RIMM, for example:http://finance.yahoo.com/q/mh?s=rimm&ql=1
